Description of ZIPP 202 NSW Carbon Clincher Rear Wheel - QR - Black

Zipp gave their top engineers in The Nest advanced development lab the task of shedding more weight from our lightest carbon clincher wheel, the 202 Firecrest, while also improving rolling friction, aerodynamics, and braking, it was a very tall order. Zipp asked them to do all of this without sacrificing durability, it looked like an impossibility. But the NSW advanced development team delivered on every request and built the ultimate climbing wheel, a climbing wheel strong enough to use on every ride.

Engineered to be the fastest accelerating carbon clincher Zipp has ever made, 202 NSW flies up the toughest climbs, and then shaves even more time off of the descents to follow. And because extracting greater speed on the mountain is only half the battle, the 202 NSW is built to deliver the lowest aerodynamic drag available for a rim of this depth for speed everywhere else.

In order for a climbing wheel to be world beating it has to do more than simply deliver low weight; it has to deliver uncompromising performance on every level. This is why Zipp engineers in The Nest chose to enhance the world’s fastest climbing carbon clincher, the 202 Firecrest.

With a new lighter carbon fiber layup for the 32mm deep 202 NSW they’ve dropped weight where it matters most, at the outer edge of the wheel, while maintaining the durability and lateral stiffness that Firecrest is famous for. Then they reduced aerodynamic drag with ABLC Sawtooth™ technology and used ImPress™ graphics to ensure that nothing stood between the air flowing over the rim and the dimples made to smooth that flow. Knowing that there is no benefit to a wheel that climbs fast and descends slow, NSW engineers incorporated our Showstopper™ brake track for the most confidence inspiring rim braking performance available, whether the road is wet or dry.

To further improve the wheels rolling efficiency, the 202 NSW rim is laced to the groundbreaking Cognition™ hubset. Built around our Axial Clutch™ freehub technology, the Cognition rear hub is engineered to maintain speed when coasting by disengaging the ratchet mechanism. This technology enables the Cognition rear hub to deliver far less rolling friction than wheels using conventional freehubs - a real advantage when fighting through rolling foothills or when spun out on long descents.

Cognition hub

Every time a conventional hubset starts to coast, friction within the freehub ratchet mechanism works like a drum brake to slow the rider down. With Cognition's Axial Clutch™ technology, we've reduced this drag by disengaging the ratchet mechanism when coasting. With less internal hub drag a rider can pedal less when drafting in a headwind, achieve higher speeds when coasting in an aero tuck, or opt to stop pedaling a moment sooner before entering a corner and bank that wattage for use exiting the corner. Axial Clutch technology also allows riders to maintain speed through corners that don't require braking input, thereby increasing corner exit speeds.

Inside the axial Clutch mechanism magnets are used rather than steel springs to move and engage Zipp's light weight Metal Injection Molded (MIM) ratchet rings for unmatched reliability and consistent operation. With 36 points of engagement that all interlock simultaneously, Cognition hubs offer one of the most secure freehub mechanisms on the market.

ImPress™

Zipp's ImPress™ technology prints graphics directly on the wheel, to help allow the dimples to do what they were designed to do - control vortex shedding, the rate at which air sheds off the wheel. Managing this is crucial to stability. Like the 808 NSW, ImPress graphics also give the NSW wheels a distinctive stealthy look while keeping the rim as light as possible.

ABLC (Aerodynamic Boundary Layer Control) Sawtooth™

The new Sawtooth™ dimple design consists of 12 nodes that are precisely clocked to start aerodynamic shearing at a rate of 50 Hz at a rider speed of 20 mph. Sawtooth™ accomplishes this by inducing small sheet vortices that shed at a low magnitude, but at a higher natural frequency, thus decreasing the laminar bubble effect on the aerodynamically shielded side of the rim's profile to further reduce high yaw drag and improve crosswind stability. That crosswind stability then imparts peace of mind when the weather turns south while saving watts that would have been expended while attempting to hold your line.

Showstopper™

When it comes to braking, "good for a carbon rim" wasn't good enough for the NSW wheels. Zipp wanted braking performance that was better than at aluminum rims, and they achieved that goal. The silicon carbide Showstopper™ brake track, which is counted among the industry leading, delivers an extraordinary stopping power and modulation regardless of weather conditions or the length of the descent. With Showstopper™ braking performance, you'll need to find another excuse not to ride on rainy days.
